Effective and selective separation of perrhenate from acidic wastewater by super-stable,superhydrophobic,and recyclable biosorbent
文献摘要：
The recovery of scattered metal ions such as perrhenate (Re(Ⅶ)) from industrial effluents has enormous economic benefits and promotes resource reuse.Nanoscale-metal/biochar hybrid biosorbents are attractive for recovery but are limited by their insufficient stability and low selectivity in harsh environments.Herein,a superstable biochar-based biosorbent composed of ZnO nanoparticles with remarkable superhydrophobic features is fabricated,and its adsorption/desorption capabilities toward Re(Ⅶ) in strongly acidic aqueous solutions are investigated.The ZnO nanoparticle/biochar hybrid composite (ZBC) exhibits strong acid resistance and high chemical stability,which are attributable to strong C-O-Zn interactions between the biochar and ZnO nanoparticles.Due to the advantages of its hydrolytic stability,superhydrophobicity,and abundance of Zn-O sites,the ZBC proves suitable for the effective and selective separation of Re(Ⅶ) from single,binary and multiple ion systems (pH=1),with a maximum sorption capacity of 29.41 mg/g.More importantly,this material also shows good recyclability and reusability,with high adsorption efficiency after six adsorption-desorption cycles.The findings in this work demonstrate that a metal/biochar hybrid composite is a promising sorbent for Re(Ⅶ) separation.
